Can anyone explain this sacrifice ?

Black sacrifices the queen to deflect the bishop away from the a4-e8 diagonal; after 2. Bxc4 Rxh2, the threat of 3...Rh1# is winning.

If Black attempts to skip 1...Qxc4+, playing 1...Rxh2?? then White wins with 2. Qxf8+ Kxf8 (2...Kh7 3. Qxg7#) 3. Re8#. Note that Re8# is guarded by the bishop in this line.

• Basically Black sacrifices the Queen to prevent White from sacrificing the Queen. The irony makes this puzzle even more brilliant.

• FWIW, it's not a forced mate but escaping will cost white a fair amount of material which will likely cost the game eventually. Apr 8 at 19:45

Always ask yourself, "what is my opponent threatening?", especially before making a move that is not a check.

Let's say Black plays the non-check 1..Rxh2. The goal is the "unstoppable" 2..Rh1# mate. But Black is wrong. Let's flip the board, and see if you can solve the resulting mate-in-2 puzzle for White:
